What Tire Pressure Saves the Most Fuel?
2 Answers
Tire pressure of 2.4-2.6 bar is the most fuel-efficient. Below are relevant introductions about tire pressure: 1 Concept: Tire pressure refers to the pressure value a tire bears, and the level of this pressure reflects the health condition of the tire. High tire pressure reduces the tire's grip, leading to longer braking distances, while low tire pressure increases fuel consumption and causes shoulder wear, making the tire more prone to blowouts. Using a Steelmate tire pressure monitoring system to monitor tire pressure in real-time can effectively prevent safety accidents caused by abnormal tire pressure. 2 Notes: There is an inverse relationship between tire pressure and fuel consumption—the higher the tire pressure, the lower the fuel consumption. However, as tire pressure decreases, the rate of increase in fuel consumption becomes more gradual. A tire pressure of 2.4-2.6 bar is the most fuel-efficient.
I always pay special attention to tire pressure when driving because it directly affects fuel efficiency. Generally, it's recommended to maintain the value indicated on the label inside the car's door frame, like the 2.3 bar written in my car. If the tire pressure is too high, say up to 2.8 bar, although the tires become harder and roll more easily, the road noise increases and the risk of a blowout rises. On the other hand, if the pressure is too low, like 1.8 bar, friction significantly increases, leading to higher fuel consumption—not to mention faster tire wear. To save fuel, it's essential to regularly check the tire pressure with a gauge, at least once a month, especially when the car is cold for accurate readings. Maintaining the standard pressure can save you 3% on fuel costs. Last month, I tried it and saved half a liter per 100 kilometers driving in the city—small savings add up over time. In short, don't expect to save fuel by simply overinflating the tires; safety first ensures long-term savings.
